The invention relates to a liquid food heating, stirring and foaming cup, which consists of a cup, a cup cover, a handle, a stirring device, a motor driving magnetic disk, a magnet, a motor, a heating disk, a parching temperature controller, a temperature controller, a microswitch, a transformer, a controller, a heating base body, a button, a button circuit board, connecting wires and screws, wherein the controller is connected with the transformer, the temperature controller, the motor and the heating disk to control the heating disk and the stirring device to work; and the liquid food heating, stirring and foaming cup drives air into liquid food to generate a great amount of foam. The liquid food heating, stirring and foaming cup makes the liquid food have better mouth feel and enriches food culture; the cup can be separated from the heating base body so that the cup is convenient to be put into a dishwasher for washing; the stirring device rotates with the motor under the absorbing action of magnetic force; when the cup is taken out, the stirring device cannot naturally drop; when the cup is arranged in the heating base body, the power is supplied; and the heating base body automatically cuts off a power supply when the cup is taken out. The cup has the advantages of reasonable design, easy manufacture and good global market foreground, makes the liquid food have better mouth feel, enriches food culture and is easy to popularize and use.
